Commelina angustifola Michx. and C. crispa Wooton, until 
more fully compared living, are continued as of specific rank. 
Both are probably better considered as geographic varieties of 
C. erecta L. 
Capsules with posterior cell more or less reduced and tardily 
dehiscent, a state which has been separated as ‘Commelina 
virginica,” are to be found in the same colonies and even upon 
the same plants with capsules normally developed, three-celled 
and evenly dehiscent. 
Flowers and fruits July to September. 
Sandy to loamy, often rocky soil, New York City, New York, 
to northern Florida, westward to Kansas and Bexar County, 
Texas; southward below the fall-line only in local heavier soils; 
locally frequent to common, especially southward. Southward 
apparently passes into C. angustifolia Michx., westward appar- 
ently into C. crispa Wooton.
